STEINHAUS, HUGO DYONIZY

STEINHAUS, HUGO DYONIZY (1887–1972), Polish mathematician. Steinhaus was one of the founders of the so-called Lvov school in mathematics; with S. Banach he founded its organ, Studia Mathematica, which he continued to edit. From 1920 to 1941 he was professor at the University of Lvov, and in 1945 became professor at Wroclaw. In 1961–62 he taught at the University of Sussex, England. Apart from serious mathematical works such as Theorie der Orthogonalreihen   ("Theory of Orthogonal Rows," with S. Kaczmarz, 1935), Sur la localisation d'objets au moyen des rayons (1938), and Sur les fonctions indépendantes (1948), Steinhaus popularized his subject in books such as Kalejdoskop matematyczny (1938; Mathematical Snapshots, 19602) and Orzel czy rzeszka ("Heads or Tails," 1961), and also wrote on the subject of establishing paternity, as in Dochodzenie ojcowstwa i alimentów (1958; Remarks … on the Establishment of Paternity and Maintenance Rights, 1958).
